Meantime to recovery (MTTR) calculations and evaluations can proactively identify your greatest business risks and help to mitigate them before a vulnerability is exploited or recovery is required.
Experts in OT Cybersecurity must participate in MTTR evaluations to achieve usable results. While the accuracy of labor and costs can be debated, category prioritization to mitigate the impacts should remain consistent. Beyond the number of systems planned for recovery there are additional considerations to reach these priorities minimally including:
- Resources and communication channels available and planned for recovery efforts
- Resilience, Disaster Recovery and Business Continuity understanding and preparedness
- Completeness and accuracy of the assets inventory and installation details
- Backup types, location, accuracy, and availability including access times
- Recovery time, verification, testing, and approvals required
When properly executed, MTTR calculations should return the following results:
- Representative duration, labor, and costs associated with recovery from a cybersecurity event
- Segregation between business continuity and return to normal scenarios
- Recommendations to reduce the organization’s exposure before an event occurs
Actions and/or Recommendations
- Evaluate your current business exposure should a cyberattack occur
- Develop recommendations for improvements before an event occurs
- Develop recommendations to improve business continuity and recovery after an event occurs
